|---|---|
| Tpes of angles | acute-angle that measures less than 90 degrees and more than 0obtuse-angle that measures more than 90 degrees and less than 180right-angle that measures 90 degreesstraight- angle that measures 180 degrees |
| angle | formed by 2 rays(sides) with a common endpoint(vertex) |
| complementary angles | 2 angles that sum to 90 degrees |
| supplementary angles | 2 angles that sum to 180 degrees |
| opposite rays | if r is between a and b then ra and rb are opposite rays |
| angle addition postulate | if point b is in the interior of aoc then the measure of measure of aob+ measure of boc= measure of aoc |
| adjacent angles | 2 angles in the same plane that share a common side and a common vertex |
